It is right with reference to embodiment and accompanying drawing for the object, technical solutions and advantages of the present invention are more clearly understood
The present invention is described in further details.Here, the exemplary embodiment of the present invention and its illustrate to be used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
During in view of evaluating seismic observation system repeatability, if requiring to obtain accurate evaluation result, need
Roll up the number for the big gun inspection pair for participating in reproducibility；If big gun is examined to that very little, can not be carried for seismic observation system
For reliable evaluation.Specifically, in this example, there is provided a kind of method for determining seismic observation system repeatability and integrally measuring,
As shown in figure 1, it may comprise steps of：
Step 101：In the range of predetermined observation system, baseline observation system and monitoring observation system are selected；
Seismic system, for time-lapse seismic system, carry out earthquake data acquisition when, it is necessary to under different situations
Seismic system be acquired.The data wherein collected for the first time are referred to as baseline geological data；It experienced a period of time
